Hmmm ... Good eye, Terry. It is probably not coincidental that this is one of the highest available alloys in molybdenum content. Moly is possibly the best fit catalyst in the periodic table, but the unalloyed metal is extremely prone to corrosion. Anyone who reads the BLP experiments with an eye towards "best fit" can see the 'usual suspects' in Column one and two of the Table. The criterion is to be as close as possible at 27.2 eV - using the confusing Mills rules of engagement, and eliminating 3-body reactions. Molybdenum ions are a good fit at 27.13 which is off by only .07 eV and this for the Mo(2+) ion; plus the miss with moly is on the low side. It seems possible, using the "energy hole" analogy, that you would want to err on the low side of 27.2 eV if you cannot hit it exactly - since the approaching hydrogen atom carries momentum. Jones
